Secure media copying and/or playback in a usage protected frame-based work

Abstract

A system and method of secure copy and/or playback control of a usage protected frame-based work is disclosed. The method includes accessing serial copy management system information for the usage protected frame-based work. In addition, the method validates the serial copy management system information. Copy management information of the usage protected frame-based work is also accessed. In so doing, the copy management information is utilized to determine if a secure copy/playback application is authorized to generate a copy of the usage protected frame-based work. Thus the copy management information acts as a technological measure which “effectively controls access to a work” by requiring the application of information, with the authority of the copyright owner, to gain access to the work.

1 . A method of secure copy control of a usage protected frame-based work, said method comprising:
 accessing a serial copy management system information for said usage protected frame-based work;   validating said serial copy management system information;   accessing copy management information of said usage protected frame-based work; and   utilizing said copy management information to determine if a secure copy/playback application is authorized to generate a copy of said usage protected frame-based work.   
     
     
         2 . The method of  claim 1 , further comprising:
 accessing playback management information of said usage protected frame-based work.   
     
     
         3 . The method of  claim 2 , further comprising:
 accessing said serial copy management system information and said usage and playback management information from at least two application-private bits of an MP3 file.   
     
     
         4 . The method of  claim 1 , further comprising:
 allowing no copies of said usage protected frame-based work if said validating of said serial copy management system information fails.   
     
     
         5 . The method of  claim 1 , wherein said copy management information comprises:
 allowing no copies of said usage protected frame-based work.   
     
     
         6 . The method of  claim 1 , wherein said copy management information comprises:
 allowing a limited number of copies of said usage protected frame-based work.   
     
     
         7 . The method of  claim 2 , wherein said playback management information comprises:
 allowing a limited number of plays of said usage protected frame-based work.   
     
     
         8 . The method of  claim 1 , wherein said copy management information comprises:
 allowing an unlimited number of copies of said usage protected frame-based work.   
     
     
         9 . The method of  claim 2 , wherein said playback management information comprises:
 allowing an unlimited number of plays of said usage protected frame-based work.   
     
     
         10 . A computer readable medium having computer implementable instructions stored thereon, said instructions for causing a compliance mechanism to perform a method of secure copy and playback control of a usage protected frame-based work, said method comprising:
 accessing a serial copy management system information for said usage protected frame-based work;   validating said serial copy management system information;   accessing copy and playback management information of said usage protected frame-based work; and   utilizing said copy management information to determine if a secure copy and playback application is authorized to generate a copy of said usage protected frame-based work.   
     
     
         11 . The computer readable medium of  claim 10 , further comprising:
 accessing said serial copy management system information and said usage restricted and playback management information from at least two application-private bits in an MP3 file.   
     
     
         12 . The computer readable medium of  claim 10 , further comprising:
 allowing no copies of said usage protected frame-based work if said validating of said serial copy management system information fails.   
     
     
         13 . The computer readable medium of  claim 10 , wherein said copy and playback management information comprises:
 allowing no copies of said usage protected frame-based work.   
     
     
         14 . The computer readable medium of  claim 10 , wherein said copy and playback management information comprises:
 allowing a limited number of copies of said usage protected frame-based work.   
     
     
         15 . The computer readable medium of  claim 10 , wherein said copy and playback management information comprises:
 allowing a limited number of playbacks of said usage protected frame-based work.   
     
     
         16 . The computer readable medium of  claim 10 , wherein said copy and playback management information comprises:
 allowing an unlimited number of copies and playbacks of said usage protected frame-based work.   
     
     
         17 . A system for secure and controlled copying and playback of a usage protected frame-based work comprising:
 a computer storage medium having instruction stored therein, said instructions when executed causing a computer system to perform secure and controlled copying and playback of a usage protected frame-based work, said instructions comprising:
 a source file receiver receiving a source file of said usage protected frame-based work, said source file having (n) copy and (n) playback management information associated therewith; 
 a destination file generator generating a destination file based on said source file of said usage protected frame-based work said destination file having (0) copy and (n) playback management information associated therewith; 
 a modified source file generator generating a modified source file based on said source file of said usage protected frame-based work said modified source file having (n−1) copy and (n) playback management information associated therewith; and 
 a validator validating said destination file and said modified source file based on said source file of said usage protected frame-based work. 
   
     
     
         18 . The system of  claim 17 , further comprising:
 a target file generator generating a target file based on said source file of said usage protected frame-based work said target file having (n) copy and (n) playback management information associated therewith, said destination file generator and said modified source file generator utilizing said target file in place of said source file of said usage protected frame-based work.   
     
     
         19 . The system of  claim 18 , wherein if said validating fails said validator deletes said target file, said destination file and said modified source file of said usage protected frame-based work and keeps said source file of said usage protected frame-based work. 
     
     
         20 . The system of  claim 18 , wherein if said validating succeeds said validator deletes said target file and said source file of said usage protected frame-based work and keeps said destination file and said modified source file of said usage protected frame-based work.
